摘要
在基于层次型体系结构的通用DCS仿真平台项目开发中 ,为了模拟不同种DCS的操作风格 ,操作界面层必须将DCS操作风格的差别集中在本层内体现 ,并屏蔽掉仪表控制层的细微差别。通过分析设计 ,在该层定义了静态图、各种动态显示、子图和各种可触发的操作目标区对象 ,实现了操作员界面的基本功能。通过对子图中数据源连接的重定向 ,解决了大多数预定义画面的实现问题。较复杂的功能可通过嵌入ActiveX控件来实现。
When developing general purpose DCS simulator which is based on a layered architecture, the operator interface layer must address most of DCS type specific features and shroud minor differences between emulated DA&C (data acquisition and control ) layer and diverse DCS products' DA&C functions. Through implementation of static graph objects (both bitmap and vectorgraph), dynamic graph element objects, child graph and triggerable target region objects, most operator interface functions are fulfilled. Redirecting data source links in child graphs can produce most of pre defined displays (templates) in DCS. Functions with more complexity can be provided through support of ActiveX controls.
